As some of you know, I want to teach my nephews some outdoor survival skills this summer and I want to get them knives. They are responsible and worthy of knife ownership. With that said. I want somthing of reasonable quality, durable, hold a good edge, fixed blade about 3in, and one that wont rust. I also dont want to spend more than $50 per knife. So........I have only thought of the Becker Necker, any others I should look into? Thanks.
